SPEGIIFIGATION forming part of Letters Patent N 0. 671,006, dated April 2, 1901.

' Application filed August 2, 1900. Serial No. 25,684. (No model.)

To all whom, it may concern.-

Be it known that I, Gnonqn A. WHALEY, a citizen of the United States, residing at Hudson, in the county of Summit and State of Ohio, have invented certain new and useful Improvements 'in'Harvester-Platforms and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention belongs to the class of foldin g platforms for harvesters and like agricultural machinery provided witha cutting mechanism to receive the mown grain, which is car ried along to one end of the platform either to be bound into sheaves or deposited in a windrow.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the appended description and drawings hereto attached.

While the essential and characteristic features of the invention are necessarily susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which Figure l is a perspective view of aplatform, showing the application of the invention. Fig. 2 is a view of the platform as it appears when folded. Fig. 3 is an end view of the means supporting the grain -Wheel. Fig. 4 is a longitudinal section of the platform near one edge. Fig. 5 is a detail perspective view of the bar applied to the front portion of the inner or fixed section of the platform. Fig. 6 is a detail perspective view of the angle-iron applied to the rear edge of the inner or fixed section. Fig. 7 is a detail view in perspective of the angle-iron applied to the rear edge of the folding section.- Fig. 8 is a detail perspective view of the angle-irons fitted to the forward edge of the inner or fixed section of the platform. Fig. 9 is a detail view in perspective of the angle-irons applied to the forward edge of the folding section of the platform. Fig. 10 is a detail view in per spective of the bar located at the forward edge of the folding section. Fig. 11 is a transverse section of the outer section of the platform adjacent to the hinge-joint formed between the sections. Fig. 12 is a detail view of one of the fastenings employed for holding the sections in alinement and the frame reference characters.

The platform comprises two sections which are hinged together, the inner section being adapted to be secured to the frame of the harvester or other implement in anysubstantial and approved way. The sections are similarly constructed and their front and rear bars are extended for attachment therewith of the frame carrying the grain-wheel, whereby the latter may be attached to the outermost end of the folding section or to the corresponding end of the inner or fixed section, accordingas the platform is either extended or folded, as shown most clearly in Figs. 1 and 2. The cutting mechanism and the traveling belt and the adj unctive parts are omit ted for the sake of clearness of illustration and may be of any make or design and adaptation, according to the size and particular purpose for which the platform is designed. The inner section of the platform is the part which is adapted to be attached directly to the frame of the harvester or other implement and comprises front and rear angle-irons 1, corresponding wooden bars 2, and a connecting-plate 3, preferably of metal, and riveted or otherwise secured at its front and rear edges to the horizontal wings of the corresponding parts 1. The wooden bars 2 are rabbeted at their inner lower edges, as shown at 4, to receive the edges of the apron. (Not shown.) Kerfs 5 extend inward from the outer ends of the bars 2 and receive inner flanges 6 of the angle-irons 1, and which flanges are formed at their outerends with knuckles and constitute hinge members. An angle- (Not - in any substantial manner.

shown.) The outer end of the angle-iron 7 terminates in line with the hinge-joint formed between the two sections. The outer end portions of the angle-irons 1 project a short distance beyond the hinge-joint between the sections to form supports for attachment therewith of the frame of the grain-wheel when the outer section is folded. The horizontal wings of the extensions of the irons 1 are formed with openings 8, elongated in the direction of the length of the irons and enlarged intermediate of their ends in conformity to the crosssection of the fastening members 9 cooperating therewith. Openings of corresponding shape are formed in the parts through which the fastening members 9 pass, a? will be described more particularly hereina ter.

The folding section of the platform comprises front and rear angle-irons 10, corresponding wooden bars 11, and a connectingplate 12, secured at its front and rear edges to the horizontal wings of the angle-irons 10 An angle-iron 13 is secured to the front iron 10 and forms a support for the cutter-bar. (Not shown.) The outer end portion of the angle-iron 13 is cut away, as shown at 14, forming a slot with the vertical wing of the angle-iron 10 to receive the forward head or iron of the grainwheel frame when the latter is in position. Flanges 15 project inward from the vertical wings of the angle-irons 10 and are provided with knuckles and constitute hinge members which cooperate with the corresponding hinge members 6 when the sections are jointed, the hinge members 15 having openings 16 corresponding in shape to the openings Sand for a like purpose. The wooden bars 11 are rabbeted at their inner lower edges, as shown at 17, for a like purpose to the rabbets 4 and are provided with kerfs 18 at their inner ends to receive the hinge members 15. The part of the wooden bars above the k'erfs 18 is cut away for a short distance to enable the outer section of the platform to fold close upon the inner section. Openings 19, corresponding in shape to the openings 8, are formed in the inner ends of the bars 11 and are adapted to register wit-h the openings 16 in the hinge members 15. The rear end portions of the angle-irons 10 project above the outer end of the platform a sufficient distance to receive the heads or irons'of the grain-wheel frame and are provided with openings 20, corresponding in shape to the openings 8 and for a like purpose. The plates 3 and 12 have their opposing edge portions overlapped, as shown most clearly in Fig. 4, and are stiffened and strengthened by angle-bars 21, located beneath them and secured thereto and to the corresponding front and rear anglerons.

The grain-wheel 22 is mounted upon an aXle 23, which is vertically adjustable, so as to effect a raising and a lowering of the outer end of the platform. A swing lever-frame 24 is provided with a thumb-latch 25 and a spring actuated latch-bolt 26, which engages with one of a series of notches 27 of a slotted guide 28, so as to hold the lever-frame in an adjusted position. The axle 23 is journaled at its ends in the members of the lever-frame 24, and its inner end is headed and passes through the slot 29 of the guide 28, so as to prevent lateral displacement of the grainwheel and its swing-frame when moved to an adjusted position. The frame having the grain-wheel applied thereto consists of a bar 30 and heads or irons 31 and 31" at the ends of said bar. The rear head or iron 31 is secured directly to the rear end of the bar 30, and a standard 32, attached at its lower end to the forward head or iron 31, is secured to the forward portion of the bar 30 and has the real-portion of the divider 33 attached thereto. The bar 30 is extended forward from the platform and has the front end of the divider 33 made fast thereto. A brace 34 connects the front end of the divider with the outer end of the angle-iron 13, and a corresponding brace 35 connects the standard 32 with an extension of the front head or iron 31. The lever-frame 24 is pivotally connected with the forward head or iron 31 and is provided at its rear end with a handle for convenience of gripping when it is required to effect a raising or lowering of the outer end of the platform. Angle-slots 36 are formed in the heads or irons 31 and 31 to correspond with a cross-section of the angle-irons 1 and 10, which are adapted to have their end exten sions snugly fitted into the said slots 36, according to the position of the grain-wheel. The body portion of the heads or irons 31 and 31 is of L shape, corresponding to the slots 36, and the wings are joined at one end by a plate 37, to which the parts 30 and 32 are rigidly attached. 'The horizontal portions of the heads 31 and 31* are formed with open ings 38 of a shape similar to the aforementioned openings 8 and for a like purpose. These openings 38 intersect with the slots 36 and are adapted to register with the openings 8 and 20, according as the frame of the grainwheel is secured to the projecting ends of the angle-irons either of the folding section or the inner section.

A leg or support 39 is pivotally connected to the outer end portion of the rear angleiron 1 and when turned into the position shown in Fig. 6 forms a support for the outer end of the inner section, thereby permitting the detachment of the grain-Wheel from the folding section. A keeper 40 is secured to the outer end portion of the rear angle-iron 1 and holds the leg or support 39 folded, as shown by the dotted lines in Fig. 6. When the parts of the platform are in alinement, the outer end of the platform is supported by the grain-wheel, the leg 39 is folded, and the sections of the platform are rigidly connected by fastenings passing through registering openings in the overlapped parts of the angle-irons adjacent to the hinge-joint, as will be readily comprehended.

The fastenings for securing the sections of the platform when alined and for holding the grain-wheel frame in position are of like formation, and a detailed description of one will suffice for a clear understanding thereof.

' 42, so as to come about flush therewith and enable the head 44 of the fastening member 9 to be passed through the registering openings in the parts to be connected. The nut 45 and washer 46 are fitted to the threaded end of the bolt 43. In practice thefastening member 9 is a trifle shorter than the distance between the extreme faces or sides of the parts to be connected, whereby provision is had for clamping said parts by screwing the nut 45 upon the threaded end of the bolt 43. When placing the fastening in position or removing it, the bolt 43 is turned so as to bring its head 44 in line with the wings 42 of the fastening member 9, thereby permitting the fastening either to be placed in the registering openings or removed therefrom. After the fastening has been positioned the parts are secured by turning the bolt 43 so as to cause its head 44 to sit crosswise of the elongated opening through which the fastening has been passed. The parts are clamped by turning the n ut 45, as will be readily comprehended.

When the sections of the platform are extended, as shown in Fig. l, the grain-wheel is applied to the outer end of the folding section, and when the platform is folded by turning the outer section upon the inner section, as shown in Fig. 2, the grain-wheel is fitted to the extensions of the angle-irons of theinnersection. When making the change that is, shifting the grain-wheel from the inner section to the outer section,or vice versathe outer end of the inner section is supported by turning the leg 39 in position, as shown by the full lines in Figs. 6 and 11.
